be used as a remote ON/OFF and a synchronization input in
both modes. Please refer to Table 3 for possible combinations
of the functions with example circuits shown in Figure 30
through Figure 40. A description of specic functions in terms
of the MULTI-FUNCTION pin I/V characteristic is shown in
Figure 11. The horizontal axis represents MULTI-FUNCTION
pincurrentwithpositivepolarityindicatingcurrentsowinginto
the pin. The meaning of the vertical axes varies with functions.
For those that control the ON/OFF states of the output such
as UV, OV and remote ON/OFF, the vertical axis represents
the enable/disable states of the output. UV triggers at I
UV
(+50 A typical) and OV triggers at I
OV (+225 A typical with
30 A hysteresis). Between the UV and OV thresholds, the
output is enabled. For external current limit and line feed-
forward with DC
MAX reduction, the vertical axis represents the
magnitude of the I
LIMIT and DCMAX. Line feed-forward with
DC
MAX reduction lowers maximum duty cycle from 78% at IM(DC)
(+60 A typical) to 38% at I
OV (+225 A). External current
limit is available only with negative MULTI-FUNCTION
pin current. Please see graphs in the Typical Performance
Characteristics section for the current limit programming
range and the selection of appropriate resistor value.
